Abstract
Electrochemical properties and interfacial stability of (PEO) 10LiCF 3SO 3 composite polymer electrolytes (CPEs) with titanium oxide (Ti n O 2 n−1 , n=1, 2) prepared by ball milling as ceramic filler are presented. The amount of titanium oxide powders introduced was between 5 and 15 wt.% into the (PEO) 10LiCF 3SO 3 polymer electrolyte. The addition of titanium oxide which consisted of plate-like spherical shape ranging from sub-micron to several microns increases the ionic conductivity by an order of magnitude compared with (PEO) 10LiCF 3SO 3 polymer electrolyte without titanium oxide, and also have the higher ionic conductivity at low temperature. Li/CPEs/50% S cells have a initial discharge capacity of between 1400 and 1600 mA h g −1-sulfur with current rate of 100 mA g −1-sulfur at 90 °C and show the higher initial charge/discharge performance than without titanium oxide. The interfacial stability was remarkably improved by the addition of titanium oxide into the (PEO) 10LiCF 3SO 3 polymer electrolyte.
